The SCX-180 can be used with fixed displacement pumps or with pressure-compensated, loadsensing variable displacement pumps and can be configured with one to ten working sections. The load sense (LS) pressure in an SCX-180 valve is generated by the compensator spool using the HUSCO patented IsoComp™ method to copy the LS signal using oil supplied by the pump instead of stealing oil from the function. Using pump oil to generate the LS signal prevents function droop at the start of metering when a function is selected. When multiple functions are selected, the SCX-180 will automatically resolve the highest function load pressure, which is then transmitted to the pump or inlet unloader (bypass compensator). This design eliminates the need for shuttles between sections, simplifying the assembly of the valve and offers excellent flow sharing capability (the valve will maintain the ratio of flows to each function, even when flow demand exceeds flow supply). Each SCX-180 valve comes with a load sense relief valve (LSRV) with an integrated pressure compensated drain function. The LS drain ensures that LS pressure drains to tank once all spools are returned to the neutral position. Each section assembly has a built-in pilot pressure supply rail and a sump rail on each side of the valve for use with electrohydraulic (EH) proportional pressure reducing valves (PPRVs). It is recommended that the sump port be plumbed directly to tank to minimize any back pressure that may affect electrohydraulic solenoid valves (a maximum sump pressure of 7 bar (100 psi) is recommended). Work port pressure limiting is accomplished by using the optional auxiliary relief valves. Each working section comes standard with auxiliary relief valve cavities machined for both work ports. See appendix page 1 for a comparison of closed center to open center valve systems. See appendix page 2 for a comparison of post-compensated to pre-compensated valve systems.

The 56903 also has an integrated pressure compensated LS drain, which drains off LS pressure when none of the spools are selected. The relief valve is protected against contamination by use of an integrated 100μ filter. The 56903 relief valve has a setting range of 62 - 300 bar (900 - 4,350 psi). The standard catalog setting for the 56903 is 214 bar (3,100 psi) and can be readjusted to suit the requirements needed for each application. WORK PORT RELIEF VALVE ASSEMBLY The 60360 Relief Valve Assembly is a direct acting relief valve with integrated anti-void (anti-cavitation) function and is the standard work port relief valve option (shock valve). The 60360 can also be used in some inlet housings to prevent fast inlet (P) pressure spikes from damaging the main control valve or the rest of the hydraulic system. Relief valves are set at 10 lpm (2.6 gpm) and have a recommended maximum flow rate of 75 lpm (19.8 gpm). The relief valve setting is stamped on the RV plug (for example: “200” = a setting of 200 bar (2,900 psi)).

The valve is protected against contamination by use of an integrated 100μ filter. PRESSURE REDUCING VALVE SHUT-OFF PLUG ASSEMBLY A series of shut-off plug assemblies are available to plug the cavity of the 58108-7 pressure reducing valve, in the SCX183-B2 Outlet Section Assembly, in case the pressure reducing valve is not required. 20 Part Number 400548 400554* 400555 Pilot Supply Source None Inlet Supply External Supply *Note: When using the 400554 Shut-Off Plug, inlet pressure must be limited to 250 bar (3,625 psi) maximum, to prevent exceeding the maximum supply pressure supplied to the PPRVs. www.huscointl.com Relief valves , end mechanisms and kits ELECTROHYDRAULIC PROPORTIONAL PRESSURE REDUCING VALVES HUSCO manufactured Proportional Pressure Reducing Valves (PPRV) are IP69 rated and come with an integrated 100μ filter on the pilot pressure supply (“B”) gallery going into the PPRV. HUSCO PPRVs work with a maximum supply pressure of 250 bar (3,625 psi). The sump port on the valve should be connected to the system reservoir with a minimum amount of back pressure (a maximum back pressure of 7 bar (100 psi is recommended). The PPRV-20-12-D-H is the standard HUSCO PPRV solenoid valve and can be used for either proportional control or on-off (“bang-bang”) control. The PPRV-20-12-D-H requires a 12 VDC control signal, comes with an integrated Deutsch DT04-2P female connector, has a 20 bar (290 psi) maximum control pressure and typically requires a 100 Hz PWM command current of 0.5 – 1.5 amp. The PPRV-20-12-A-H requires a 12 VDC control signal, comes with an integrated Amp Junior Power Timer male connector, has a 20 bar (290 psi) maximum control pressure and typically requires a 100 Hz PWM command current of 0.5 – 1.5 amp. See HUSCO PPRV literature for more technical details. Consult HUSCO Sales department for non-standard electrical connectors or coil voltage requirements. ELECTROHYDRAULIC CONVERSION ASSEMBLY KIT The 61482-1 Conversion Kit will plug the EH solenoid cavity on EH sections and provides a 9/16-18 (SAE 6) o-ring port for connecting pilot pressure to the spool spring chamber in order to shift the spool as a hydraulically pilot operated section. The kit allows a section assembly to be “electrically prepared” (machined for PPRV solenoid valves but built to be hydraulically pilot operated). When a customer wants to update from pilot operated control to EH control, the section can be easily upgraded to EH in the field without the need for a costly valve removal. 21 www.huscointl.com Relief valves , end mechanisms and kits ADJUSTABLE FLOW CONTROL KIT The SCX-180 adjustable flow control works by providing an adjustable orifice that can regulate the flow of a full flow spool from approximately 60 lpm (15 gpm) to 150 lpm (40 gpm). Due to the extra restriction that is added with the adjustable flow control assembly, the maximum flow rate of a given spool is reduced when the flow control is installed. The graph below shows the flow adjustment range with standard SCX-180 spools when using the adjustable flow control assembly. The flow control is most effective with full flow spools. When used with lower flow rate spools, the range of adjustment decreases. Assembled into the compensator bore in place of the standard compensator spool and plug assembly, the adjustable flow control assembly and compensator can be installed into an existing section assembly, making it ideal for vehicle upgrades or retro-fits in the field. Flow Control Assemblies are available with a plastic “rabbit-turtle” knob, or with a steel shaft for connection to an adjustment shaft.

It can be used to limit the maximum flow of a given spool or as a fine tuning mechanism when trying to match the flow from sections or work ports exactly, and it is compatible with both hydraulically pilot operated electrohydraulically operated sections. The 61538 Manual Override Kit provides a way to manually shift a spool far enough to lower a machine implement in case of a dead engine situation. It also provides the function of the adjustable stroke limiter and allows the manual override adjustment to be made independent of the stoke limiting adjustment.

The following table compares the system costs and efficiencies of an open center system, a closed center system with unloader (bypass compensator) and a closed center system with a pressure-compensated load-sensing variable displacement pump. Open Center System • Fixed displacement pump • Pressure differential across spool depends on flow System Cost Efficiency $ Unloader (Bypass Compensator) System • Fixed displacement pump • Unloader (bypass compensator) spool diverts excess flow • Constant pressure differential maintained Pressure Compensated Load Sense System (PCLS) • Variable displacement pump • Load sensing valve • Pump flow varied to maintain constant pressure differential www.huscointl.com $$ 25 $$$ A ppendix 2 Post- compen S ated versus pre -compensated The following hydraulic circuits represent the basic design of post-pressure compensated and pre-pressure compensated closed center valve systems. There are several differences in the two styles of valve design, which are determined by the basic valve geometry and design. The most noticeable difference however, is that post-compensated valves continue to offer excellent flow sharing when flow demand exceeds flow supply, while pre-compensated valves will only meet the flow demands of the lowest loaded functions (causing higher loaded functions to slow down or stop moving). Traditional Post-Pressure Compensated Circuit Key Features: • Pressure differential acting on the compensator spool is picked downstream of the main spool metering orifice • Load sense signal from each function is picked up before the load sense shuttle • All compensator spools reference the same resolved load sense signal – Key feature for maintaining flow sharing • Pump to load sense pressure differential is controlled by the pump or the inlet unloader (bypass compensator) Resulting Characteristics: • When flow demand exceeds flow supply, the compensators will split the pump flow to all functions proportional to the main spool metering orifice of each spool – Great flow sharing, even when exceeding flow supply. • Maximum function pressure is limited using optional auxiliary relief valves – Load Sense pressure limiting on individual functions is not available Traditional Pre-Pressure Compensated Circuit Key Features: • Pressure differential acting on the compensator spool is picked from either side of the main metering orifice • Load sense signal from each function is picked up after the load sense shuttle • Compensator spools reference a load sense signal picked up before the load sense shuttle – Allows load sense pressure limiting on individual functions • Pump to load sense pressure differential is controlled by the compensator springs 26 Resulting Characteristics: • When flow demand exceeds flow supply, the lowest loaded functions will take priority over the highest loaded function – Highest loaded functions may stop moving, depending on flow demand www.huscointl.com order sheet MO DE L S C X -
